[0002] As an important component of artificial protection of coastal ports, breakwaters can block the impact of waves, enclose harbors, and maintain a stable water surface to protect ports from bad weather. At the same time, breakwaters can also provide security for ports, ensure the stability of the port's water level, and meet the needs of ship berthing, loading and unloading operations, and entry and exit navigation. The existing methods mainly determine the relative arrangement distance of the breakwater column group through wave simulation analysis and structural stability analysis, including the use of physical models or numerical simulation software to simulate the propagation, reflection, and diffraction of waves in front of the breakwater, and stability analysis of the column group structure. By calculating the stress conditions of the column group at different arrangement distances, the optimal arrangement scheme is determined to ensure the stability and safety of the structure.

[0003] However, the propagation, reflection and diffraction process of waves in front of the breakwater is a complex physical phenomenon, which is affected by many factors. The accuracy and resolution of the existing model are difficult to capture all the key physical phenomena, resulting in differences between the simulation results and the actual situation; and when conducting stability analysis on the column group structure, it is necessary to consider the effects of various external loads. The calculation of these loads is itself a complex problem, which requires accurate wave data and structural parameters. These factors may lead to inaccurate analysis results; therefore, there are still problems with the cost and difficulty of breakwater construction. It is difficult to reduce the construction difficulty and preparation time, and it is impossible to improve the wave reduction effect of the column group breakwater while saving costs.

This fusion method can make full use of the information of the two types of features to generate a more representative feature set, which helps to improve the prediction accuracy of subsequent models.

[0099] S1.5. Set a time window, calculate the weight value according to the relevant wave data of the wave parameter data in the time window, and continuously update the weight value as the time window slides to obtain the wave weight parameter;

[0100] Fuzzy sets are defined for the two objectives of minimizing the impact effect of waves on the column group and maximizing the stability coefficient of the column group, and several fuzzy sets including the fuzzy set of the impact effect of waves on the column group and the fuzzy set of the stability coefficient of the column group are obtained; and membership functions are constructed for each of the fuzzy sets in the fuzzy sets, and several membership function sets are obtained; among them, the fuzzy set of the impact effect of waves on the column group is a mapping from the actual impact effect value to the fuzzy set, and the mapping range is from 0 (no impact) to 1 (maximum impact), and the fuzzy set is used to describe the size of the impact effect of waves on the column group, and the smaller the value, the smaller the impact effect; the fuzzy set of the stability coefficient of the column group is a mapping from the actual stability coefficient value to the fuzzy set, and the mapping range is from 0 (lowest stability) to 1 (highest stability), and the fuzzy set is used to describe the level of the stability coefficient of the column group, and the larger the value, the higher the stability;

[0101] Based on wave weight parameters and several membership function sets, a multi-objective optimization function is constructed.

[0102] Among them, "the impact effect of waves on the column group" refers to the dynamic force or pressure generated when the wave contacts and acts on the column group, and the "stability coefficient of the column group" is an indicator used to measure the stability of the column group structure when subjected to external forces; and several membership function sets include the impact effect fuzzy set membership function and the stability coefficient fuzzy set membership function, specifically:

Defining fuzzy sets for the two goals of minimizing the impact effect of waves on the column group and maximizing the stability coefficient of the column group helps to deal with the uncertainty in these goals. A membership function is constructed for each fuzzy set so that the specific value of each goal can be mapped to a membership between 0 and 1. This helps to balance these two potentially conflicting goals during the optimization process.

The adaptive mechanism refers to dynamically adjusting these parameters according to the historical search performance of the particles and the state of the current search space. For example, when the particle swarm is close to the global optimal solution, the inertia weight is reduced to strengthen the local search; when it falls into the local optimum, the acceleration factor is increased to promote the particles to jump out of the local optimum.

[0112] In the auxiliary particle group, a combination operation is performed on several elite particles and a mutation operation is performed on several elite particles to obtain an auxiliary global optimal solution; wherein several elite particles are obtained by dividing the auxiliary particle group according to the fitness value of the particles;

[0113] The global optimal solution and the auxiliary global optimal solution are substituted into the multi-objective optimization function for calculation, and the objective function values ​​of the global optimal solution and the objective function values ​​of the auxiliary global optimal solution are obtained respectively. These objective function values ​​are compared to evaluate the performance of different solutions in terms of optimization objectives; the global optimal solution or the auxiliary global optimal solution with better objective function value performance is defined as the actual optimal solution, and the actual optimal solution is output as the final model prediction result of the optimal relative arrangement distance of the column group, and a specific construction plan of the column group breakwater is generated according to the final model prediction result of the optimal relative arrangement distance of the column group.

[0114] Use professional structural analysis software (such as SAP2000, ANSYS) to model and analyze the structure under the optimal relative arrangement distance of column groups; evaluate the overall stability and safety of the structure by calculating parameters such as displacement, stress and strain of the structure, so as to obtain the evaluation results of the engineering value; use the preset cost estimation software to estimate the costs of materials, labor, machinery, etc. according to the design plan of the optimal relative arrangement distance of column groups, so as to obtain the evaluation results of economic benefits.

[0115] In this embodiment S1.6, by setting the main particle group and the auxiliary particle group, the search space is effectively divided.

The meta-learner can be trained by using several intermediate models and a parameter indicator set established according to the query set performance stability index, the inter-task knowledge transfer metric and the meta-learning weight adjustment factor. This method can comprehensively consider information from multiple aspects, so that the meta-learner can learn the characteristics of the data more comprehensively and accurately.

[0163] The function unit is also used to define fuzzy sets for the two objectives of minimizing the impact effect of waves on the column group and maximizing the stability coefficient of the column group, and obtain several fuzzy sets including the fuzzy set of the impact effect of waves on the column group and the fuzzy set of the stability coefficient of the column group; and construct a membership function for each fuzzy set in the several fuzzy sets, and obtain several membership function sets; wherein the fuzzy set of the impact effect of waves on the column group is a mapping from the actual impact effect value to the fuzzy set, and the mapping range is from 0 (no impact) to 1 (maximum impact), and the fuzzy set is used to describe the size of the impact effect of waves on the column group, and the smaller the value, the smaller the impact effect; the fuzzy set of the stability coefficient of the column group is a mapping from the actual stability coefficient value to the fuzzy set, and the mapping range is from 0 (lowest stability) to 1 (highest stability), and the fuzzy set is used to describe the level of the stability coefficient of the column group, and the larger the value, the higher the stability;

[0164] The function unit is also used to construct a multi-objective optimization function based on wave weight parameters and several membership function sets.

[0165] Among them, "the impact effect of waves on the column group" refers to the dynamic force or pressure generated when the wave contacts and acts on the column group, and the "stability coefficient of the column group" is an indicator used to measure the stability of the column group structure when subjected to external forces; and several membership function sets include the impact effect fuzzy set membership function and the stability coefficient fuzzy set membership function, specifically:

Defining fuzzy sets for the two goals of minimizing the impact effect of waves on the column group and maximizing the stability coefficient of the column group helps to deal with the uncertainty in these goals. A membership function is constructed for each fuzzy set so that the specific value of each goal can be mapped to a membership between 0 and 1. This helps to balance these two potentially conflicting goals during the optimization process.
